    e1000e: fix PHY init workarounds for i217/i218 · 4e03510b
    Bruce Allan authored Jan 04, 2013
    
    
    Toggling the LANPHYPC Value bit cycles the power on the PHY and sets it
    back to power-on defaults.  This includes setting it's MAC-PHY messaging
    mode to use the PCIe-like interconnect, so the MAC must also be set back
    from SMBus mode to PCIe mode otherwise the PHY can be inaccessible.
